Detailed Description
The embodiment of the invention solves the technical problem of avoiding the whole vehicle from being deficient in power caused by failure of OTA upgrading by providing the OTA upgrading method and the OTA upgrading device.
In order to better understand the technical scheme of the present invention, the following detailed description will refer to the accompanying drawings and specific embodiments.
The OTA upgrading method of the embodiment of the invention is applied to TBOX, and as shown in fig. 1, the OTA upgrading method comprises the following steps:
step S1, after the OTA installation condition check is passed, a third request for holding a lock for a third duration sent by an OTA component is received;
step S2, judging whether TBOX is in normal mode;
step S3, if the TBOX is in the normal mode, locking the TBOX for a third duration based on the third request;
step S4, after successful locking is fed back to the OTA component, information of a third duration of TBOX locking is recorded;
and S5, after the OTA upgrading task is completed within the third time, clearing the information of the TBOX locking third time.
The OTA upgrading process in the embodiment of the invention comprises the following steps: when the vehicle is started and the vehicle speed is low, if the TBOX downloads the OTA upgrade package to be completed, an IVI (n-Vehicle Infotainment, vehicle-mounted information entertainment system) of the vehicle can display an upgrade task popup, a user can select upgrade reservation time on the upgrade task popup, the IVI records the upgrade reservation time and sends the upgrade reservation time to the OTA component, the OTA component sets the upgrade reservation time, and after the OTA component sets the upgrade reservation time, the TBOX records the upgrade reservation time;
after the upgrade reservation time is reached, if the TBOX is not awakened normally, the OTA upgrade task is not started, and the OTA upgrade task is continued to the next day; if the TBOX wakes up normally in the upgrade reservation time, controlling the TBOX to switch from sleep mode to normal mode (normal working mode), sending a first request for holding a first lock duration (such as 90 s) to the TBOX by the OTA component, applying for the first lock duration of the TBOX, checking an upgrade package by the OTA component by the TBOX 90s, after receiving the first request, holding the TBOX for the first lock duration based on the first request, and feeding back success of holding the lock to the OTA component; because the TBOX can enter a dormant state under the condition of no task, the lock holding is to prohibit the TBOX from dormancy and maintain the whole vehicle to wake up; then the OTA component checks the upgrade package, after the check is passed, the OTA component sends a second request for holding the lock for a second duration (such as 900 s) to the TBOX, and the TBOX holds the lock for the second duration, and the TBOX holds the lock for 900s for the OTA component to check the OTA installation condition;
after the TBOX receives the second request, locking the TBOX for a second duration based on the second request, then performing OTA installation condition checking by the OTA component, after the OTA installation condition checking is passed, sending a third request for locking a third duration (for example, 3 hours) to the TBOX by the OTA component, applying for locking the TBOX for the third duration, and locking the TBOX for 3 hours to complete the OTA upgrading task.
In the traditional OTA upgrading method, after receiving a third request, the TBOX records information of a third duration of locking of the TBOX, and then judges whether the TBOX is in a normal mode or not; if the TBOX is in the normal mode, enabling the TBOX to be locked for a third duration based on the third request, feeding back success of locking to the OTA component, and then completing the OTA upgrading task; if the TBOX is not in normal mode, the TBOX feeds back to the OTA component that the locking is unsuccessful, and the whole vehicle enters a dormant state. And after the next day TBOX day is restarted and initialized, calling the information of the third duration of the TBOX lock holding recorded in the previous day, judging that the instruction for prohibiting the TBOX from dormancy for 3 hours is effective, and then executing the instruction for prohibiting the TBOX from dormancy for 3 hours, so that the whole vehicle is kept to wake up for 3 hours, and the whole vehicle is caused to be deficient in power.
In the embodiment of the invention, after the TBOX receives the third request, the information of the third duration of the TBOX lock is not recorded first, but whether the TBOX is in the normal mode is judged, if the TBOX is in the normal mode, the information of the third duration of the TBOX lock is recorded after the TBOX lock is successfully locked is fed back to the OTA component, after the OTA upgrading task is completed in the third duration, the information of the third duration of the TBOX lock is cleared, so that the information of the third duration of the TBOX lock is not recorded after the OTA upgrading failure, the recorded information is cleared after the OTA upgrading success, the information recorded after the TBOX restarting is no longer existed, long-time awakening of the whole vehicle is not caused, and the whole vehicle power shortage caused by the OTA upgrading failure can be avoided.
In the OTA upgrade procedure in the embodiment of the present invention, a situation may occur that the OTA component sends the first request first, and then the TBOX switches from sleep mode to normal mode, i.e., when the TBOX receives the first request, the TBOX has not switched to normal mode yet, which may cause the TBOX to fail to hold the lock for the first time, and the OTA component cannot check the upgrade package. To avoid failure of the TBOX to lock the first time period, the OTA upgrade method may further include, before step S1:
after the TBOX wakes up at the upgrade reservation time, controlling the TBOX to switch from a sleep mode to a normal mode, and receiving a first request for holding a lock for a first duration sent by an OTA component; judging whether the switching time of the TBOX from sleep mode to normal mode is earlier than the receiving time of the first request; if the switching time is later than the receiving time, feeding back a lock holding failure to the OTA component, so that the OTA component sends a first request based on a feedback loop until the switching time is earlier than the receiving time; if the switching time is earlier than the receiving time, locking the TBOX for a first duration based on the first request; checking that the OTA upgrade packet passes in the first time length by the OTA component, and receiving a second request for locking a second time length sent by the OTA component; the TBOX is locked for a second duration based on the second request such that the OTA component performs an OTA installation condition check for the second duration.
After the TBOX feeds back the lock holding failure to the OTA component, the OTA component sends a first request to the TBOX every 1s until the TBOX switches to normal mode or repeatedly sends 15 first requests, so that the first time period failure of the TBOX in lock holding can be avoided.
In the above flow, after the TBOX is switched to normal mode, the situation that the first request is not sent all the time due to the abnormality of the OTA component may also occur, and if the OTA component is waited for to send the first request all the time, the TBOX is caused to remain meaningless and wake up, and the electric energy is wasted. To avoid the TBOX remaining meaningless awakening, the OTA upgrade method may further include, after the upgrade reservation time awakening: judging whether a first request is received within a preset duration; if the first request is not received within the preset time period, the TBOX is made to enter a sleep mode. The preset duration may be 15s, so that if the first request sent by the OT component is not received within 15s, the TBOX is dormant, and the TBOX is prevented from being awakened meaningless.

In the traditional OTA upgrading method, after receiving a third request, the TBOX records information of a third duration of locking of the TBOX, and then judges whether the TBOX is in a normal mode or not; if the TBOX is in the normal mode, enabling the TBOX to be locked for a third duration based on the third request, feeding back success of locking to the OTA component, and then completing the OTA upgrading task; if the TBOX is not in normal mode, the TBOX feeds back to the OTA component that the locking is unsuccessful, and the whole vehicle enters a dormant state. And after the next day TBOX day is restarted and initialized, calling the information of the third duration of the TBOX lock holding recorded in the previous day, judging that the instruction for prohibiting the TBOX from dormancy for 3 hours is effective, and then executing the instruction for prohibiting the TBOX from dormancy for 3 hours, so that the whole vehicle is kept to wake up for 3 hours, and the whole vehicle is caused to be deficient in power.
In the embodiment of the invention, the receiving module does not record the information of the third duration of the TBOX holding lock after receiving the third request, but the judging module judges whether the TBOX is in the normal mode, if the TBOX is in the normal mode, the holding lock module makes the TBOX hold lock for the third duration based on the third request, the feedback module feeds back the information of the third duration of the TBOX holding lock to the OTA component, the recording module records the information of the third duration of the TBOX holding lock again after the success of the holding lock, and the clearing module clears the information of the third duration of the TBOX holding lock after the OTA upgrading task is completed within the third duration, so that the information of the third duration of the TBOX holding lock is not recorded after the OTA upgrading failure is no longer recorded after the OTA upgrading success, the recorded information after the TBOX is restarted again does not exist, the long-time awakening of the whole vehicle is not caused, and the whole vehicle power consumption caused by the OTA upgrading failure can be avoided.
In the OTA upgrade procedure in the embodiment of the present invention, a situation may occur that the OTA component sends the first request first, and then the TBOX switches from sleep mode to normal mode, i.e., when the TBOX receives the first request, the TBOX has not switched to normal mode yet, which may cause the TBOX to fail to hold the lock for the first time, and the OTA component cannot check the upgrade package. In order to avoid failure of the TBOX to hold the lock for the first time, in the OTA upgrading device:
